IMPROVEMENT IN SIGN-PLATES.

Specification forming part of Letters Patent No. 169,680, dated November9, 1875 application filed September 13, 1875.

To all whom it may concern Be it known that 1, HIRAM T. DEWEY, ofBrooklyn, in the county of Kings and State of New York, have invented anImprovement in Sign-Plates, of which the following is a specification:

Signs have heretofore been made of a metal plate, with openings cut inthe same to form letters and numbers, and in some instances the openingshave been tilled with glass prisms, and in other cases the plate, witheither open letters or solid letters in a frame, has been applied tostreet-lamps.

My invention relates to a sign made of thin sheet metal cut out like astencil-plate; and consists in combining with the same a sheet or sheetsof mica to close the openings in the plate, and a sheet-metal frame,that surrounds the plate and the mica, and serves to confine themtogether, and give sntficient stiffness t0 the sign or name plate forhandling the same with facility.

In the drawing, Figure 1 is an elevation of the said sign, and Fig. 2 isa section of the same.

The thin sheet-metal plate a is cut out with 4 the name or number, orboth, that may be desired for a sign or name plate, and this is done thesame as a stencil-plate, so as to leave the necessary connecting-bars.The plate ot' mica b is of a size corresponding to the metal plate a,and may be composed of more than one piece Ot'miea, according to thesize of the sign, and mica may be put upon both sides, if desired. Thesheet-metal frame dis made of a folded strip, that surrounds the sign,and clamps the metal and mica together, and stiffens the sign. The micais not liable to be' HIRAM T. DEWEY.
